How to choose anti-static products in the semiconductor industry
In the semiconductor device production workshop, the output of VLSI will be greatly reduced due to dust adsorption on the chip. Operators in the production workshop wear clean work clothes. If the human body is full of static electricity, dust and dirt are easily absorbed. If these dust and dirt are brought to the operation site, the product quality will be affected, the product performance will be deteriorated, and the yield will be greatly reduced. If the radius of the adsorbed dust particles is larger than the width of the line and the film thickness is low, the product is most likely to be scrapped.
Therefore, it is necessary to establish an electrostatic protection system during processing, production and packaging. Integrated circuit packaging production lines have stricter requirements for static electricity. In order to ensure the normal operation of the production line, the cleaning workshop should be completely decorated with anti-static building materials, and all personnel entering and leaving the cleaning workshop should be equipped with hardware measures such as anti-static clothing. In addition, packaging enterprises can formulate enterprise standards or specific requirements for anti-static according to relevant national standards and the actual situation of the enterprise to cooperate with the normal operation of the packaging production line.
Due to the wide variety of electrostatic dedusting equipment, how to choose a suitable product mainly depends on the conditions on the production line. Several devices that can remove dust and static electricity are described below:
1. Ion Air Gun: It is hand-held and easy to operate. It is more suitable for use on inspection site. The inspector just has to pick up the air gun and when he sees there, he can blow up the dust.
2. Ion air nozzle: It is a fixed product with small size and no space. Ion air nozzles are more suitable for workstations on assembly lines or some narrow spaces. It can also be made into pedal type and induction type. Ion air nozzle
3. Ion Wind Snake: There are three styles: ordinary, induction and pedal, which can meet the needs of customers in different environments on the production site. The ion wind snake is suitable for stations that have space to be placed and do not require personnel to operate, but the direction of dust blowing needs to be adjusted frequently.
In addition to the above products, ion fans should be installed in some assembly lines and operation stations to reduce the accumulation of static electricity and prevent products from being punctured unintentionally. We can choose our suspended ion blower, which has a large power consumption area and does not take up work space, which can be selected according to the size of the workbench or the width of the assembly line.
